Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi)

Bukhari :: Book 5 :: Volume 59 :: Hadith 611

Narrated Abu Qatada:

When it was the day of (the battle of) Hunain, I saw a Muslim
man fighting with one of the pagans and another pagan was hiding
himself behind the Muslim in order to kill him. So I hurried
towards the pagan who was hiding behind the Muslim to kill him, and
he raised his hand to hit me but I hit his hand and cut it off.
That man got hold of me and pressed me so hard that I was afraid
(that I would die), then he knelt down and his grip became loose
and I pushed him and killed him. The Muslims (excepting the Prophet
and some of his companions) started fleeing and I too, fled with
them. Suddenly I met 'Umar bin Al-Khattab amongst the people and I
asked him, "What is wrong with the people?" He said, "It is the
order of Allah" Then the people returned to Allah's Apostle (after
defeating the enemy). Allah's Apostle said, "Whoever produces a
proof that he has killed an infidel, will have the spoils of the
killed man." So I got up to look for an evidence to prove that I
had killed an infidel, but I could not find anyone to bear witness
for me, so I sat down. Then it came to my mind (that I should speak
of it) and I mentioned the case to Allah's Apostle. A man from the
persons who were sitting with him (i.e. the Prophet), said, "The
arms of the deceased one whom he ( i.e. Abu Qatada) has mentioned,
are with me, so please compensate him for it (i.e. the spoils),"
Abu Bakr said, "No, Allah's Apostle will not give it (i.e. the
spoils) to a weak humble person from Quraish and leave one of
Allah's Lions who fights on behalf of Allah and His Apostle."
Allah's Apostle then got up and gave that (spoils) to me, and I
bought with it, a garden which was the first property I got after
embracing Islam.
